Pavel, Thank you, that is very informative. My internet connection is just fine with the exception of all things that are related to OpenCPN.org (tracker, web & wiki).

My "theory" is as follows:
1. Either Veerotech or my provider is exercising its new rights to throttle and limit my access to opencpn. IE my modem's IP has been added to their XXXX list.
2. Why? Because I executed some php plugin code for the wiki that may have been incompatible with another plugin and all holy hell broke loose, and my screen went blank.

I expect that when I get to Boston it will work because it is a different modem, (also opencpn.org works on our cell phones.). My question is how long will this condition last? Do I have to actually do something about it to get it fixed or will it be "fixed" in time? Because I am going to need it working in about a week.

I think I will call our ISP and ask them to bring up opencpn.org to see if they are having DNS problems with that server.

Also I've used a kind of network tool that visually traces the entire ping, which might be useful to see for opencpn from this modem.

Thanks Thomas, I can do that. It eats up minutes on my data plan. I think it is a veerotech nameserver issue. "Missing nameservers reported by parent".
I can ping with success in reasonable time, but tracerroute does not work.
